Hello All;

I have an intel s5000psl
For the last few weeks it has been randomaly shutting down on its own.
The latest time, was sometime early this morning.
When I tried to boot it back up, it would...

I would toggle the on/all switch on the PSU
And it would do the [Amber/Green] in 3 sets.
Then it would cycle on all the fans for about 2-seconds and then stop.

I completely removed everything from the board, and tested.
1-CPU / 1-Ram module
And still the same thing.

Took a break, and then came back, and wa-la, it booted with both CPU's and 2-sticks of ram.
So, I added in the remainder of the ram modules and it booted up and ran for about 20-minutes and then shut back down again.
I have not been able to get it to book back up since. (Been trying this go around for about 2-hours. Re-seating the memory and everything and still no go)

Is it the PSU (or) is the MB board?

Thanks for any information.

Hello everyone,

I have no idea how this laptop developed a cracked screen and have been using it for the past two years but just wondering if we could get the screen replaced as the touch screen functionality doesn't work on the left side of the crack.

Anyway, contacted Dell support regarding this and their recommended part number DT2CR costs a total of $221 which is obviously a very expensive replacement for an old laptop.

Could someone recommend something similar at Amazon or eBay? That would be tremendously helpful.

Thank you so very much for your time.

I'm looking to get a new UPS for my office. I'm trying to determine the best route to go with the UPS I purchase. I currently have three Dell Ultrasharp u2412M LED Monitors, a Dell T5400 PC, a Dell Latitude D5430 laptop with a docking station for the laptop, Logitech speakers and sub woofer, phone, wireless headset, and charger for iPhone and mini ipad for my music. I want to get a UPS that will support the monitors, PC, docking station for my laptop, speakers/sub woofer and charger. The phone and wireless headset would be nice, but isn't necessary.

I was looking at the following UPS:

Would this support all those devices? Would I need more battery back up than that? Should I get smaller UPS, but several of them to support the various devices...i.e. one for the monitors, one for the PC/docking statation/laptop, and one for speakers and charger?

I'm trying to determine the ideal configuration to support the devices using a UPS. Any recommendations would be appreciated.

Hello Experts:

I'm adding a Radeon VEGA 56 Video Card to a desktop system.  The stock power supply is 280 Watt.

The machine has an AMD A10 9700 3.5GHz Processor and a 512GB SSD HDD.  32GB RAM

Will this work or do I need to upgrade the power supply?


I am new to Angular and using Angular 6 CLI. Problem I have is, I have a JSON object that I am getting data from http.get and then trying to parse out different JSON blocks in an object. Then I am passing these objects to respective components. I can see that in the subscribe block the data is populated correctly but outside subscribe block, those objects are 'undefined'.

So from any .ts file, the objects outside subscribe block is undefined. However, I could access data from template files that is from .html files.

for example,  below is where I am calling service from "Component A" so component A has "myappRoot", "myapp", "myproblem"..etc all objects of custom type defined. The custom type is basically interface which I am exporting from index.d.ts file. So objects are populated  inside subscribe block is fine. But if I do console.log(this.myproblem) it comes as undefined outside ngOnInit(). If I pass this object to "Component A HTML" file like {{ this.myproblem? | json}} it prints correctly. but if I pass it to some other component B like <app-component B [myproblem] = 'this.myproblme' ></app-component B> and try to do console.log(this.myproblem) in component B.ts file, it comes as undefined.  Is it due to async nature of observables? How do I solve this?

ngOnInit() {
    // lets  make a call and initialized the root object and children
    this.myproblemService.getmyproblem().subscribe(root => {
      this.myappRoot = root;
      this.myapp = root.myapp;

Dear experts,

I have wireless keypad for my laptop -windows 10.

I use it both for my  normal text typing as well as for c language.

Is there a separate set-up required for keypad when using it for typing languages syntax (for instance || and \)

The reason is I do see the key strokes on the keypad but when I type it types different characters.

Kindly guide me to switch between these two requirements.

Thank you

I built a desktop.  When I switch on the power and push the power button, the system fans come on but nothing else seems to come on.  Also, the system fans only come one when the 24 pin power cable is plugged in.  If I unplug the 24 pin and just plug in the 8pin CPU power, nothing happens.  No display activity, no USB activity, either way, they are plugged in.  Everything is brand new.

First, should I be plugging both in?  One thing I have noticed is that the motherboard is a Gigabyte Z370N WIFI with has a 4 pin heat sync plugin.  I have a Corsair H55 heat sync which has a 3 pin plug.  Since the motherboard is designed for a four pin plug, I wonder if that is why nothing will turn on?  See the image of the motherboard specs.

Also, one thing to note, when I turn on the power switch on the back, a light flashes on the motherboard once quickly, then nothing.  But as mentioned before, as long as the 24 pin cable is plugged in, the system fans still stay on.  

Another Test: Tested the ThermalTake TR2 Power supply with the 24pin Paperclip test. The fan in the Power Supply runs just fine.

I am installing a Gigabyte Z370N Motherboard with a Powerspec 430 power supply.  I have connected the main 24 pin power connector, but I was wondering if I needed to connect an additional power connector for the CPU?  It looks like there is an 8 pin connector on the Motherboard.  I have a split 6pin / 2 pin and a 4 pin connector.   Do I need to connect to it, I'm not sure which cable to connect or what slot. Do I connect the 4 pin to the 6 pin connector?  If so,Gigabyte Z370N WIFI which side?  See image.
Dear Experts

Asus Motherboards will not boot.  CPU fan spins for 5 seconds then stops, no post, no beeps.  Have tried multiple CPUs, multiple RAM sticks, multiple power supplies, and 3 different Chassis.  I've also bench tested this (MB/CPU/RAM/PSU) without success.  This happens with 5 motherboards, all the same type, brand new from ASUS: Z370-G.  I've swapped all the components I can think of.  Any Experts can think of something I missed?  It's hard toi believe an entire box of MBs is bad, but seems to be leaning that direction.


We have an APC AP9631 network card for a UPS that I think is defective. When I assign it an IP address through the front panel of the UPS, the settings don't save. I replaced the card with another one and it works.

APC wanted me to try doing a remote connect through a serial cable but that didn't seem to work. Now we have had to send the UPS to site and I can't get to it anymore.

APC says they haven't confirmed the card is defective so can't replace it. Has anyone seen the behaviour above and were still able to fix it?
This works on an access form.

=Nz(DLookUp("[Rebate]","Rebates",("[foo]=[foo] and ([DMS]) Between [MSH] And [MSL] And ([DDoses]) Between [VH] And [VL]")),0)

But in a complicated scenario I need it to operate to update a table after a value is changed on another part of the form.
I've tried for days and I can't get it to work.  

Rebate, DMS and DDoses are numbers while foo is text

Here, I'm trying to just break it down into components to isolate anything.

Dim db As Database
Set db = CurrentDb

Dim xfoo As String
Dim xDMS As Long
Dim XDDoses As Long
Dim varx As Long

xfoo = Forms!PST.Form![PST1 Subform]![foo]
xDMS = Forms!PST.Form![PST1 Subform]![DMS]
XDDoses = Forms!PST.Form![PST1 Subform]![DDoses]

varx = DLookup("[Rebate]", "[Rebates]", "[foo]= " & xfoo)

DoCmd.RunSQL "Update PST1 Set PST1.Cohort = '" & varx & "'"
What is the name of the type of power plug connector for a Lenovo Ideapad Yoga 910-13IKB laptop?

I need to recommend an external battery charger for this type of laptop from the list below and want to be sure I choose one that is fully compatible and will be able to be plugged into this type of laptop.

The serial number for this Lenovo laptop is PF0QV5V6.
I am looking for a dock that reads old IDE, Ultra IDE, and also old smaller laptop HDs as well as any type of SATA HDs.  I would prefer one with a USB 3.0 connection.  I've looked all over and haven't been able to find someone that offers one.  One other option that I just thought of would be to use some type of converter with it with one end of the converter going to the HD and the other end going to the dock.  Example old IDE drive connected to the converter and then the converter connected to the dock.  Please advise if you can find a dock that will connect them directly with the dock and if there are converters available, and if so, will they work with a dock.

We need to order a replacement scanner and have found this scanner for sale on Amazon:

(which is identified as an "EPSON 1680 - EPSON PERFECTION 1680 W/ADF" scanner.

We need to make sure that we order the exact same model scanner.

I have already asked this question on Amazon but haven't yet received a reply.

I have an EPSON Expression 1680 scanner that won't power on.

I have replaced the power cord with several known good power cords and have plugged this scanner into different power plugs but it still won't power on.

What can I do to troubleshoot or fix this issue?

Does this scanner have a fuse or similar item that can be replaced that might fix this issue?

Attached is the manual for this scanner.

Please provide me with the URL addresses orFRU numbers I can use to purchase a second battery pack for Lenovo Ideapad Yoga 910-13IKB Laptop so that I can have a total of two batteries connected to my Lenovo laptop at the same time.

The serial number for this laptop is PF0QV5V6.
Machine is HP Pavilion HPE h8-1100z
BIOS is corrupted by malware.
No access to OS, installing new OS not possible.

How can one recover (re-flash) the BIOS?
From an USB drive yes, but HP's Hardware Diagnostics utility does not support any of the Pavilion HPE for BIOS recovery..
Has anyone recovered the BIOS on a Pavilion HPE lately? The BIOS update exe (from HP support site) does not offer anymore the option of creating an USB drive.

Any other option other than recycling this expensive machine?
I have a new Samsung Galaxy S9 which replaces a Samsung Galaxy S6 and I have two issues which are probably connected:

a) I cannot use the App "Wifi File Transfer Pro" - when I launch the App on the phone it gives an IP address to enter into my browser on the PC, but when I enter this address it will not bring up the page - the connection eventually times out; on the Galaxy S6 this works perfectly

b) I have an app I have written in Java which has components running on the phone and my PC, which I use for transferring various files between the phone and my PC - again this has worked perfectly for many years on the Galaxy S6, but on the S9 it fails to connect:  the phone component successfully wakes up the PC component which does its thing and then tries to connect to send the result, but the java command connection=new Socket(host, PORT) times out with the error message " Connection timed out: connect"

It looks like a firewall issue, but it's not the firewall on my PC since I've tried disabling that temporarily.   It may be a firewall issue on the Samsung S9 but I can't see how to configure that.   I've tried tweaking the Setting "Phone visibility" but that doesn't seem to solve the issue.

Any thoughts?

I have an old psi which I want to convert to a 12v power supply for some led lights.
 The problem is that in cleaning out the dust before I got started the green wire has broken off the board.
 Where does it solder back onto as I cannot identify where it broke off from.

 Thanks for your help in advance.
